SECTIONAL CUSHION-TIRE.

IPECIFICATIN formingpart of Letters Patent No. 735,993, dated August 11,1903.

- `Application filedv September 29. 1902.4V Serial No. 125,247. (Nomodel.)

To all whom it may concern,.-

Beit known that I, CHARLEs MILLER, a

citizen of the United States, residing at Binghamton, in the county ofBroome and State of New York, have invented certain new and usefulImprovements in Sectional Cushion- Tires, of which the following is aspecification. y

This invention relates towheels having sectional cushion-tires; and itconsists in certain improvements in the construction of such tires, ashereinafter describedand claimed.

In the accompanying drawings, Figure l. is a perspective View of aportion of a wheel-rim embodying the features of my-invention.

2 is a longitudinal section through the same, showing my cushiontirewith the corey of sponged rubber cured into the outer casing, so as toform one piece with it. Fig. 3 is a section on the line 3 3 'of Fig. 2.Fig. 4 is a detail view of one of the T-bolts. Fig. 5 is a perspectiveView of a modified form of my invention as adapted for a regular orcrescent wheel-rim, such as is in general use for pneumatic tires,showing a crescent-shaped strip of wood on which the sections of mycushiontires are to rest. Fig. 6 is a longitudinal section through thesame. Fig. 7is a section on the line 7 7 of Fig. 6. Fig. 8 is a detailView of the T-bolt used in the construction shown in Fig. 5. Fig. 9 is adetail perspective of still another modification. Fig. IO is a detailsection thereof, and Fig. ll is a detail perspective view.

Referring to thedrawings, A'designates a channeled wheel-rim'on which ismounted one' section of my cushion-tire.

B indicates the outer casing of a section of my rubber tire with a beador flange I at its base.

C indicates a sponged-rubber core that is cured into the outer casing,so as to form one piece with it. The curing is done in the followingmanner: The outer casing is built up of fabric and rubber with a bead atits base. It is then put into the mold and semicured. The iron core thatis in the outer casing when it is semicured is then removed from theouter casing and sponge-rubber is put in its place. The mold is put backin the vulcanizer and finished curing or the outer casing may be builtup of fabric and rubber with a bead at its baseandthe sponge-rubberplaced inside of it and put into the mold and all cured together. Ineither "case the core or sponge rubber placed inside is cured into theouter casing, so that it cannot be removed, or, in other Words, it isall in onev piece with the outer casing.

' D indicates the half-caps in thechanneled rim. These half-caps (ordivided cap) cover or press each side ofthe sections E and force themdown into the channel of the rim, which channel holds the half-capstogether on the sections.

F indicates the T-bolts that draw the halfcaps down onto the iianges ofthe rubber sections and into the channeled rim.

G (shown in Fig. 5) indicates a strip of wood, crescent-shaped, whichfits into the crescent rim H and makes a flat surface on which to restmy sections of tire when it is desirable to use them on Wheels havingcrescent-shaped rims.V

The caps or half-caps D rest on the flanges I of. the sections E,.whileat each end of the caps the T-bolts F rest on and draw them down intothe rim and also prevent them from eyes M, corresponding to those in theends of.

the half-caps, which plate is designed to rest on the ends of thehalf-caps, and bolts N go `through this plate and through the holes oreyes in the ends of the half-caps and draw them down onto the flanges ofthe sections and into the channeledrim. N indicates the bolt passingthrough the plate and the ends of the half-caps, and O indicates the nutby which said bolt is made fast to the inner peripheryofthewheel-rim.Adiiferentconstruction of a T-bolt is shown on Fig. 8, with ends Padapted to prevent the half-caps from falling apart and to draw thesections down onto the base of the rim.

IOO

I claim-f l. The combination with a channeled rim, of a cushion-tirefitted therein and made up of independent sections, each of which hasend and side fianges within the rim, open caps snugly embracing therespective tire-sections and resting against the flanges with theirabutted endsprovided withregisterednotches, and T-bolts passing throughthe openings formed by th'e registered notches and also piercing therim, the heads of the bolts overlapping the abutted ends of' the caps.

2. The combination with a channeled rim, of a cushion-tire fittedtherein and made up of independent sections, each of which has oppositeend and side flanges within the rim, open caps snugly7 embracing therespective tire-sections and bearing upon the flanges thereof with theirabutted ends provided with registered notches, each cap being formed inopposite longitudinal sections with the joint therebetween intersectingthe notches at the ends of th'e cap, and T-bolts passing through theopenings formed by the notches and also piercing the rim, the heads ofthe bolts lying transversely of the rim and overlapping the abutted endsof' the caps.

The combination with a channeled rim, of a cushion-tire fitted thereinand made up of independent sections, each of which has opposite end andside flanges within the rim, open caps snugly embracing thetire-sections and bearing upon the fianges thereof with their abuttedends reduced in thickness and provided with registered notches, andT-bolts passing through the openings formed by the registered notchesand piercing the rim, the heads of the bolts being disposed transverselyof the rim and seated snugly in the seats formed by the reduced abuttedends of the caps.

4. The combination with the crescent rim of a wheel of a crescent-shapedstrip of' wood, adapted to fit into'said crescent-shaped rim, sectionsof cushion-tire with resilient centers cured into them and resting onsaid strips of' wood, capseither in one piece, or divided to formhalf-caps, resting on the flanges of the sections, T-bolts resting onthe ends of said caps and drawing them down onto the flanges of saidsections and into the crescent rim.

5. The combination with a channeled rim,

remesa of a strip fitted therein and provided with a flat outer face, acushion-tire fitted in the rim and made up of independent sectionsresting against the fiat face of the strip, each section having oppositeend and side flanges within the rim, individual caps resting against therespective tire-sections and having central openings through which thebodies of the tiresections project, and T-bolts extending between theopposite ends of the adjacent caps and piercing the rim, with the headsof the bolts lying transversely across the rim and overlapping the endsof the caps.

G. A tire, embodying a casing having its opposite longitudinal edgesformed for connection with a rim, and a sponge-rubber core cured intothe casing.

7. A tire embodying a casing made up of fabric and rubber, with itsopposite longitudinal edges formed for connection with a rim, and asponge-rubber core cured into the casing.

8. The combination with a rim, of' a cushion-tire madeup of independentsections, caps embracing the respective sections, and formed inlongitudinal sections, and T-shaped fastenings having their headsoverlapping the ends of the sections and their stems secured to the rimto hold the caps in place.

9. The combination with .a rim, of a cushion -tire made up ofindependent sections, caps embracing the respective tire-sections andformed in longitudinal sections, the abutted ends of the adjacent capsbeing reduced and notched, and fastenings, consisting of heads fitted inthe seats formed by the abutted, reduced ends of the caps, and stemspassing through the notches and the rim.

lO. The combination with a channeled rim, of a strip fitted snugly inthe rim and provided with an outer flat face, a tire fitted fiat againstthe strip and made up of independent sections, caps embracing therespective tiresections, and headed fastenings piercing the rim and thestrip with their heads engaging the ends of the caps to hold the same inplace.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES MILLER.
